NUT-LOCK.

Specification of Letters Patent.

Patented Mar. 9, 1915 Application filed July 29, 1314. Serial N 0.853,848.

To all whom it may concern Be it' known that I,'J0HN G. GannAno, acitizen of the United States, residing at High Point, in the county ofGuilfo'rd and State of North-Carolina, have invented certain new anduseful Improvements in Nut- Locks; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to new and useful improvements in devices forlocking nuts and is particularly designed. for use in connection withrail joints and resides in the provision of simple, effective andinexpensive means that will positively hold a nut against negativerotation.

Another object is to provide a nut lock device that maybe easily andquickly applied to a rail joint without necessitating any change in theconstruction of the rails or fish plates at the joint and which willprove durable and efficient in'operation and inexpensive to manufacture.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out as claimed.

With reference to the drawings wherein I have illustrated the preferredembodiment of my invention as it is reduced to ractice and throughoutthe'several views 0 which similar reference numerals designate cor-'responding parts, Figure 1 is a side elevation of rails joined with myimproved nut locking device, Fig. 2 is alongitudinal sectional viewtaken through Fig. 1', 3 is a vertical'sectional view taken transverselyon'l ine 3-3 of Fig. 1, and Fig. 4'- is'a detail'perspective w of theone of the nut locking plates. r I

Referring't'o the drawings by e aracters of reference, the numei'als 1and 2 "es ignate the rails at a joint and 3 and 4 fish plates of theordinary cohstrhction. Mounted upon opposite sides of the rails 1 and 2upon the fish plates are rectangular spacing-plates 5 and 6 that are ofapproximately one-third the length of the fishplates and are directly1212 553 29 9 3 eeeth form w th openings adjacent to the endsthereof toreceive bolts 7 and 8. The bolts 7 and 8 are inserted through the rail.webs, fish plates and alined openings in the member 5 and 6 with theirheads resting upon the outer face of the plate 6 and havenuts 9 turnedon their threaded terminals and resting upon the'oute'r face of theplate 5.

'Mounted upon the outer face of the spacing plate 5 is a nut lockingplate designated 10 generally and which is rectangular and ofapproximately the same width, thickness and length as the plate 5. Thisplate 10 is provided at each end with square openings I 11 to receivethe nuts 9 on the bolts 7 and 8.

countersunk within the inner face of the plate 5 centrally of said plateand extending eyond the outer face of the plate is a pin 12 that isprovided with a beveled head 13 which head is countersunk as described.The locking plate 10 is provided with a central opening 11 that isdesigned to receive the pin 12 and in assembling the device the plate 10is positioned so that the pin 12 finds the opening 14 and if the nutsare in theproper position the openings 11 in said plate 10 will receivethe nuts and the nuts are thus held against rotation.

A cotter pin 15 is inserted transversely through'the outer end of thepin 12 and holds the plate 10 securely upon the plate 5. Mountedupon theouter face of the spacing plate 6 is a locking plate 16 which isrectangular and of approximately the same length as the fish plates.This plate 16 is provided with-a central opening 17 which is designed toreceive a'pin 18 that is identical with the pin 12 and secured to theplate 6 in the same manner. A cotter pin 19 is inserted through the pin18 to hold the plate 16 in position. cent to its ends as at 20 and saidofi'set portions'extend inwardly and are designed to engage the 'rails 1and 2 on the under faces of "the balls and upper faces of the bases ofthat allof the plates are beveled on their longitudinal edges so as toconform to the shape of the under face of the ball and upper face of thebase of each rail. In

each of the offset portions is formed a rectangular or square opening 21that is de- 'The plate 16 is offset adja- .the'rails. 'In thisconnection it will be noted openings 21 in the offset portions 20 of thelocking plate 16 and are held securely against rotation;

Adjacent to the central plate 16 is formed a pair 0 ings 24. Each of theopenings 24 is enlarged inwardly toward the 'inner"- face of said plateso that when the plate is positioned the heads of the bolts 7 willengage within the openings 24: but will be countersunk as clearly shownin Fig. 3 in the drawings when said plate 16 is secured in locking position. This arrangement insures the looking action since the heads ofthe bolts are protected as well as the nuts on the opposed ends thereof.

It will be readily seen that rails when joined with nut locking devicesof my inrproved form will be securely locked against derangement andthat the nut and bolts will remain in proper position under allconditions. To remove my improved lock it is only necessary to withdrawthe cotter pins 1-9 and 15 so that the plates 10 and 16 may be removed.All of the plates including the fish plates of my improved device engagethe under face of the balls and upper faces of the rails thus a rigidjoint is provided as well as a locking of the nuts.

In practice, I have found that the form of my invention, illustrated inthe drawings and referred to in the above description, as the preferredembodiment, is the most eflicient and practical; yet realizing that theconditions concurrent with the adoption. of my device will necessarilyvary, I desire to emphasize the fact that various minor changes indetails of construction, proportion and arrangement of parts may be resorted to within the scope of the claims when required, withoutsacrificing any of the advantages of myinvention, as set forth.

What is claimed is 1., A nut lock 'in combination with fish plates of arail joint, spacing plates mounted upon said fish plates and opposed toone another, pins having heads countersunk in the inner faces of saidspacing plates and projecting outwardly from said plates, lock ingplates having central openings therein to receive said pins and providedwith openings adjacent to each end of angular formation to receive nuts,one of said look-- ing plates being longer than the other and providedwith o enings to receive the heads of bolts, bolts inserted through therails and plates, nuts turned on said bolts, all of said nuts beingdisposed within the openings to receive the nuts and held against ro-1fportion of the circular opentation, and certain of the headsof saidbolts being, disposed within the longer locking plate.

. 2. The combination with the rails ofa rail joint, and fish platesmounted on opposite sides of said rails, of spacing plates of lesslength than. the fish plates mounted upon opposed sides of the rails andon thefish plates, pins removably secured to the spacing plates andextending outwardly therefrom, locking plates having central openingstherein to receive said. pins, one 01: said locking plates beingapproximately the same length as the spacingplates and hav ing squaredopenings adjacent to its end, the other of said locking plates being approximately the same length as the fish plates and having squaredopenings formed therein adjacent to its ends, bolts inserted through therails, fish plates and outer ends of said last named locking plate, nutsturned on said bolts and to be received within the openings in the outerends of said last named locking plate, said last named locking platehaving its ends ofiset inwardly and provided centrally of its ends withspaced openings that are enlarged in-- wardly, bolts inserted throughthe fish plates, locking plates and spacing platesand havin their headsdisposed within the last name openings in said last named locking.

plate, nuts turned on said last named bolts and disposedwithin thesquared openings.

in said first named locking plate and cotter. pins inserted transverselythrough theouter ends of the pins carried on said. spacing plates. I

3., i In a nut lock the combination with the fish plates of a railjoint, spacing plates mounted upon said fish plates, pins carried bysaid spacing plates, locking plates having central openings therein andpolygonal openings in the ends thereof mounted upon the spacing platesand having the pins received in the central openings therein, one ofsaid locking plates being longer than the other and having its endsofiset inwardly,v
